5 5. Aquatic environments have a number of sources of pollutants. Pollutants from point sources come from specific places that can be easily identified and controlled. Non-point sources of pollutants are widespread, they usually cover a large area and cant be easily measured or identified. The following table identifies some types of pollutants and their sources. Point sources Non-point sources Pollutant Mines Wastewater treatment plants Stormwater Agriculture pathogens (bacteria and viruses) toxicants (heavy metals and pesticides) sediments nutrients (nitrates and phosphates) salinity heat Which statement is correct according to the information in the table? (A) (B) (C) (D) Wastewater treatment plants are n-point sources of toxicant and nutrient pollution. All listed sources of pollutants release sediment and pathogens into aquatic environments. Mines and agriculture release the largest volume of pollutants into aquatic environments. While the table shows different pollution sources, the volume of each pollutant is t shown.

10 QUESTION KEY KEY REASONING LEVEL OF DIFFICULTY 1 D 2 D 3 D 4 B 5 D Start at the top of the diagram. The satellite s diameter of km is greater than the diameter of the Earth s moon (3 500 km), but less than Mercury s diameter of km. The table identifies the characteristics of flowers that attract particular animals. The key classifies some flowers according to their characteristics. To arrive at the correct answer you must match the characteristics from the key to those given in the table. For the strings to remain unbroken, the strength of each string must exceed the mass it is required to support. That is, the top string must be capable of supporting the total mass of the three weights, the middle string must be capable of supporting the mass of the two weights beneath it, and the bottom string must be capable of supporting the mass of the bottom weight. This occurs only in option (D), where string Z (capable of supporting 10 kg) is supporting three weights with a total mass of 9 kg, string Y (capable of supporting 5 kg) is supporting two weights with a total mass of 4 kg, and string X (capable of supporting 3 kg) is supporting a mass of 1 kg. As methane has smell, D is wrong. Because methane is less dense than air it will float upwards, so A is wrong. While methane is flammable, this will t hinder getting methane into the flask, so C is wrong. Wastewater treatment plants are point sources of pollution, so A is wrong. According to the table, wastewater treatment plants do t release sediments, so B is wrong. The table only shows the type of pollution and its source; there is information in the table that shows the correct volume of pollution produced, so C is wrong and D is correct. Easy Easy Medium/Hard Medium/Hard Medium/Hard LEGEND Level of difficulty refers to the expected level of difficulty for the question. Easy Medium Medium/Hard Hard more than 70% of candidates will choose the correct option. about 50 70% of candidates will choose the correct option. about 30 50% of candidates will choose the correct option. less than 30% of candidates will choose the correct option.
